Answer:
Distance, x = 73.10 meters
Explanation:
It is given that,
Mass of the rock, m = 25 g = 0.025 kg
Acceleration due to gravity, a = 1.62 m/s²
We need to find the distance traveled by the rock when it falls from rest in 9.5 seconds if the only force acting on it was the gravitational force due to the Moon. It can be calculated using the second equation of motion i.e.
x = 73.1025 meters
or
x = 73.10 meters
So, the distance traveled by the rock is 73.10 meters. Hence, this is the required solution.
Answer:
Objects that are not moving have NO velocity and momentum (only)
Explanation:
This best explains the potential energy of an object, when an object is at rest. it is said to have possessed a potential energy but without velocity and momentum i.e energy at rest
To find the density of an object you would use the formula density = mass x volume, or d=mv. The answer to your question is 14515.2.
Answer:
Depends on the capacity of battery. Mostly our phones flashlight can be used up to 8 to 10hrs continuosly
Explanation:
Capacity of the battery is level to which battery is charged, & amount of current drawn by the flashlight, you can calculate the answer yourself if u know the capacity of that light.
Moreover you can calculate this by using equation,
E =Pt
So, for time
t=E/P
Batteries are rated in Amp hours, like 10 amp hours will supply us 1 amp for 10 hours
2 amps will give us 5 hours

Answer:
coefficient of static friction is 1.7329
Explanation:
given data
velocity = 60 mph
acceleration = 17 m/s²
to find out
coefficient of static friction
solution
we will apply here centripetal force equation
that is
m×v²/r = µ × m × g ..................1
here v²/r is centripetal acceleration and m is mass and µ is coefficient static friction so
µ = a / g
µ = 17 / 9.81
µ = 1.7329
so coefficient of static friction is 1.7329
